ok im going against the trend, but my opinion is that Nero is crap, and nero express is worse simply cause of the fact that it only recognises it's own multisession disc's, quite often when I burn disc's with another program, and like to add files, using nero it will not import the previous sessions cause it didn't write them, it will write my file and rewrite the TOC. And lo and behold all that is on the disc is my one file I just burned GRRR!!...

I use CloneCD for cd to cd copies, and RecordNow Max for files etc... (and since this came with my pioneer dvd writer)..
works quite well.

cheers,
Jai
